AGnIcnnruRAL IMPLEMENT.

To all whom it may concern:

Be it known that-we, JAMES .E. MCLAUGI-I- LIN and DONAT BononLEAU, subjects ofthe King of Great Britain, residing at Grand mere, in the Province of Quebec and Dominion of Canada, have invented certain new -:and useful Improvements in Agricultural Implements, specification. l a

This invention relates to agricultural implements, and more. particularly to those of which the followingis a having interchangeable blades or tools.

The primary object of the invention is to so construct an implement of this character that the blade ortool thereof may be readily adjusted at various angles to adapt it to perform different functions and which is interchangeable with other blades'to adapt it for different uses. Another object is to so construct an implement of this character that the blade thereof maybe set at any desired angle to adapt it for use by a short or a tall person andtwhich', by changing the adjustment will adapt it to be used for'difi'erent. purposes.

i Still another object is to construct a de-1 vice of thischaracter. which is simple in construetion, cheap to manufacture, and in which the blades may be quickly changed.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combiimplement constructed in accordance with this invention, a rake head being shown in this form of the invention,

Specification of Letters Patent.

I ble the width of the detail of the shank, a portion of the handle being sho n connected Patented July 2, 1918.

7 Application filed June 28, 1917. Serial No. 177,540.

Fig. 6 is a detail perspective view of the clamping member, and

Fig. 7 is a detail perspective view of a hoe blade designed to be changed with the rake head shown in the other figures.

In the embodiment illustrated-in Figs. 1 tol4, the tool employed is in the form of a rake head 1 having the usual teeth 2 and a I tang '3. This tang 3 rises vertically from the rake head midway the ends thereof and has a quadrant shaped arm 4 provided at its free end with laterally extending journals as 5 designed for a purpose presently to be described. -These journals 5 are shown arranged at the lower or inner edge of the quadrant shaped arm, and a threaded stud 6 extends upwardly from said arm at a point opposite the journals as is shown clearly in Fig. 4 and which is designed for a purpose presently to be described.

A handle H of ordinary construction is here shown provided with a ferrule F in which is inserted one end of a shank 7 as is shown clearly in Fig. 1. This shank 7 has an offset head 8 provided with a pair of laterally spaced semi-circular arms 9 and 10, the straight inner edges of which have bearings in the form of notches 11, the bearing in one arm registering. with that in the other and which are designed to receive the journals 5 of the tool head, the quadrant shaped arm 4 of which is designed to be positioned between the arms 9 and 10 of the shank and the threaded stud 6 of which pro-' jects beyond the curved edges of the arms 9 and 10 andis designed to receive a clamping element .12 which is held in position by a wing nut 13 screwed on said stud 6.

The curved edges of arms 9 and 10 are provided with a plurality of transversely extending peripherally spacedribs 16, those on one arm registering with those on the" other and these ribs are shown of uniform width throughout the greater portion of the series, but those at the rear thereof are douin Fig. 1.

The clamping element 12 is constructed of a metal plate having an aperture 14 for the passage therethrough of the stud 6 and at its opposite edges has laterally extending flanges 15 spaced aparta distance sufficient others as shown at 16' tween said fureations and provided With In testimony whereof we affix our signalaterall extendmg journals adapted to be tures in presence of two witnesses.

rotatab y engaged with the bearings of said shank, and means carried by said tan for 5 detachably en aging the notches in sai furcations where y the tool may be adjusted Witnesses: and held at difierent angles in relation to JOSEPH DESCHAMPS, the shank. ADELOR BORDELEAU.
